There are four main reasons that determine when to replace them: 1 To upgrade performance; 2 to restore the vehicle’s designed performance (usually after 50,000 miles); 3 when the vehicle has excessive ride control conditions i. Nose dive, body roll, etc. ; or 4 when the vehicle has a failed unit i. Dripping hydraulic fluid, tire cupping, excessive bounce, etc. Testing has shown that original equipment gas-charged shocks and struts degrade measurably by 50,000 miles. Unlike a tire, which rotates a specific number of times per mile, a shock absorber or strut may compress and extend several times per mile on a smooth road, or several hundred times per mile on a very rough road. There are other factors that affect the life of a shock or strut, such as, regional weather conditions, amount and type of road contaminates, driving habits, loading of the vehicle, tire / wheel modifications, and the general mechanical condition of the suspension and tires. Why to replace worn shocks or struts? Performance degrades slowly over time. When shocks and struts aren’t controlling tire and body movement very well due to wear, all ride control conditions are affected. Stopping ability will be reduced. Tire performance is reduced and because of excessive movement, all other attached steering & suspension components are affected. We carry a wide range of shocks and struts. Every shocks and struts we carry is TS16949 certified. They are made to meet or exceed OEM quality. If you couldn’t find the item you need, please send us a message.
